<h2>控制器布局</h2>

<p>一种在 Laravel 使用模板的方法是通过控制器布局。通过在控制器中指定 <code>layout</code> 属性，指定的视图将为您创建并被作为函数的响应。</p>

<p><strong>在控制器中定义一个布局</strong></p>

<pre><code>class UserController extends BaseController {

    /**
     * The layout that should be used for responses.
     */
    protected $layout = 'layouts.master';

    /**
     * Show the user profile.
     */
    public function showProfile()
    {
        $this-&gt;layout-&gt;content = View::make('user.profile');
    }

}
</code></pre>

<p><a name="blade-templating"></a></p>

<h2>Blade 模板</h2>

<p>Blade 是 Laravel 提供的一个简单但很强大的模板引擎。不像控制器布局，Blade 由<em>模板继承</em>和<em>切片</em>驱动。所有 Blade 模板应该使用 <code>.blade.php</code> 文件后缀。
<strong>定义一个 Blade 布局</strong></p>

<pre><code>&lt;!-- Stored in app/views/layouts/master.blade.php --&gt;

&lt;html&gt;
    &lt;body&gt;
        @section('sidebar')
            This is the master sidebar.
        @show

        &lt;div class="container"&gt;
            @yield('content')
        &lt;/div&gt;
    &lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p><strong>使用一个 Blade 布局</strong></p>

<pre><code>@extends('layouts.master')

@section('sidebar')
    @parent

    &lt;p&gt;This is appended to the master sidebar.&lt;/p&gt;
@stop

@section('content')
    &lt;p&gt;This is my body content.&lt;/p&gt;
@stop
</code></pre>

<p>注意 <code>extend</code> 一个 Blade 布局的视图将覆盖布局中的切片。布局中的内容可以在子视图的切片中使用 <code>@parent</code> 指令被包含进来，允许您添加布局中的内容比如侧边栏或者底部。</p>

<p><a name="other-blade-control-structures"></a></p>

<h2>其他 Blade 控制结构</h2>

<p><strong>显示数据</strong></p>

<pre><code>Hello, {{ $name }}.

The current UNIX timestamp is {{ time() }}.
</code></pre>

<p>为了对输出内容进行转义，您可以使用三花括号语法：</p>

<pre><code>Hello, {{{ $name }}}.
</code></pre>

<p><strong>If 结构</strong></p>

<pre><code>@if (count($records) === 1)
    I have one record!
@elseif (count($records) &gt; 1)
    I have multiple records!
@else
    I don't have any records!
@endif

@unless (Auth::check())
    You are not signed in.
@endunless
</code></pre>

<p><strong>循环</strong></p>

<pre><code>@for ($i = 0; $i &lt; 10; $i++)
    The current value is {{ $i }}
@endfor

@foreach ($users as $user)
    &lt;p&gt;This is user {{ $user-&gt;id }}&lt;/p&gt;
@endforeach

@while (true)
    &lt;p&gt;I'm looping forever.&lt;/p&gt;
@endwhile
</code></pre>

<p><strong>包含子视图</strong></p>

<pre><code>@include('view.name')
</code></pre>

<p><strong>显示语言行</strong></p>

<pre><code>@lang('language.line')

@choice('language.line', 1);
</code></pre>

<p><strong>注释</strong></p>

<pre><code>{{-- This comment will not be in the rendered HTML --}}
